To all whom t may concern,

Be it, known thatl I, ALBAN H. REU), a citizen of the United States, residing at `Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certainsnew and useful Tmprovements in Pasteurized-Liquid-Holding Apparatus, ot' which the following is a specitication, reference being had therein to the accompanying drawing.

This invention relates to pasteurizing apparatus and more particularly to a pasteurized-liquid holding device for holding heated A0r pasteurized milk for a predetermined time to 'ettect thorough and complete destruction of bacteria.

The invent-ion comprises, gene ally, a suitable receptacle or housing divided into a series of com artments t'ormed by spaced partitions eac 1 partition being provided with a liquid-receiving holder or trough, from the base of which extends a pipe or tube the receptacle being further provided with means for circulating the liquid through and discharging the same from the receptacle, and with means for successively emptying the respective compartments. The invention comprises, more specitically, a suitable housing or receptacle, preferably to form a cylindrical chamber in which arc arranged at intervals suitable partitions dividing the chamber into a number ot compartments each partition having disposed at one side, and preferably at its upper end, a trough or the like, from the base ot which a pipe or tube extends downwardly and alongside the partition, discharging atI the bottom ot' the chamber into the compartment in which the pipe is located the receptacle being also provided with suitable feed and discharge pipes which lead into and outl of the chamber, and with mcans t'or emptying cach compartment.

The invention consists. also, construction and arrangement of parts, hereinafter fully described and claimed.

ln the accompanying drawings, Figure 1 is a view in perspective ot' the holding device, with a portion ot' thc'lront walt there- 2 is a vertical longitudinal section of thc same taken on the line u--a ot' Fig. il; ltig. il is a vertical transverse, section taken on the line b--b of Fig. 2; and Fin'. t is a perspective view ot one ot' the partition-members detached.

In these drawings, 1 designates a receptacle or housing mounted upon supporting in the novel and escape therefrom` at the feet or standards 2. As a matter of convenient and effective arrangement, the receptacle 1 is appioximately cylindricalin form, and is provided at its upper portion with a hinged closure 3 of appropriate construction and arrangement to provide tor absolutely air-tight closing ot' the housing and the retention of the heat of the. treated liquid. Leading into the 'receptacle at yone end is a feed-pipe l for introducing the pasteurized milk therein` the portion 4 within the receptacle extending downwardly to near the bottom of the same. as shown. At the opposite end of the receptacle isa stand-pipe 5 provided at its upper end with a tunnel 5, or the like. The stand-pipe constitutes a means ot' discharge from. the receptacle. and is removably mounted in a liquid-tight coupling member 5b. from which extends a discharge pipe or nozzle 5C.

lVithin the receptacle are disposed, at intervals` partitions or plates (S, equidistantly arranged to div' le the chamber into a series ot compartments T; the edges of the plates being connected liquid-tight to the walls of the chamber. Each partition has, at its upper end. a holder or trough S, trom the base ot which extends downwardly a semi-circular pipe or tube tl alongside its respective partition and discharges at its lower end into the base of the compartment in which it. is located. as shown. The front Vall 8 ot the holder or trough is relatively lower than the opposite wall S ot said trough. llach partition` at its lower end, is )rovided with au opening therethrough closed by a valve or other controlling device which may, as shown, be in the torm ot a plug or yalve, S". adapted to be removed trom the opening by hand or otherwise.

Assuming that thc valves S in the sclvc al partitions are closed and that the closure 3 is in closed position. the heated milk or other liquid.. ted in through the feed-pipe et, enters the tirst comlmrtment' and tills it.

lh'cntually, the milk will overflow the low trough, and then half-round pipe 9 bottom, into the wall S and pass into the downwardly through the the next compartment. 'l`hereupon. milk will and pass over the low wall ot the next trough. and then into the next compartment: and so on throughout the series. when all ot' the compartments become titled and the milk rises in the last one, it tinds its discharge ,through the upper cnd vofthe rise in thissecond compartment the lasticompartment to become filled.

stand-pipe 5, through which it flows downwardly and escapes through the discharge pipe or nozzle 5c into a cooler or receptacle.

In the operation of the apparatus, the milk from the pasteurizer at the usual temperature of from 140 to 145 F. is fed con-v the'milk passing through the apparatus is therefore subjected for a period of thirty minutes tofthe temperature at which it entered, which action is suflicient to destroy all the pathogenic organisms therein.

After the supply ofgmilk to the receptacle has been cut ofi and, when the level ofthe milk, in the last compartment, falls below the discharge stand-pipe, the compartments will be left filled. Some means must. be provided therefore for emptying the apparatus. This is effected by removing said stand-pipe -from the coupling-member 5" and successively opening the valved 'orifices in the lower portion of the several' partitions, beginning with that nearest the standpipe. The milk or other liquid will, then, Ifiow directly through the valved oi enings and out through the discharge nozzle or pipe 5C. i

, It will be understood that while my invention is utilized particularly for milk, it is also capable of use in connection with other pasteurized liquids.

An important feature of this improved holding device is that the milk docs not itequire tobe heated in the pasteurizer to a. higher temperature than from llt) to 145O and, by being held approximately thirty minutes at this temperature, more valuable results are accomplished than by healing the milk to a temperature ot lrom tot) to lofi". Moreover, the device provides l'or a thorough circulation o'l the'milk, and by maintaining it at the lspecitied temperz'ttnrc. l'or approximately thirty minutes, only an almost inappreciable decrease in temperature results, from the time the milk enters the holdetinntil it is discharged.

lt is knowntthat, il' milk is permitted lo set 'for any time, the cream thereotl is liable to rise to the surface. ',l`he provision. therefore, o'l the trough al. the upper end ol' each partition is that they may pert'orm an important Alunction: As already described, the milk rises in the respective compartment and overllows into the trough and, thence, through the pipe or tube tt into the nextsucceeding compartnient. ln this tiortn ot' overflow-trough, the cream'llows t'rom thesurface of the milk into` the trough and is carried down to the bottom of the next compartment, the milk following the cream in its downwardffiow, whereby the cream is kept constantly mixed with the milk, in each compartment and thereby 'avoiding all necessity of stirring, as usual, and which would, of course, disturb the general and uniform tiow of the milk through the holding device. -W'hile I have herein described my invention in detail, it is to be understood that I do not limit myself to such details except in so far as .they may be specified in the claims.

Having thus fully described my invention, what I desire to secure by Letters-Patent is:

1. yIn a pasteurized-liquid holding apparatus, the combination of a receptacle provided with inlet and outlet openings, a plurality of partitions'dividing the receptacle into a series of compartments'.` lateral elongated collecting troughs en the partitions communicating with the upper portion of one compartment, each of said troughs having a contracted channel leading downwardly therefrom and communicating at its lower end at or near the base of the next compartment, and means for circulating the pastenrized-liqnid through said compartments.

2. In a pastenrized-liquid holding apparatus, the combination ot' a receptacle provided with inlet and outlet openings, a plurality o'tl partitions therein dividing the receptacle into a number ol compartments, lateral elongated shallow collecting troughs at the upper end ol the compartments each communicating with the upper portion of l one compartment, and a pipe leading downwardly from e'ach ol' thetrouglis and communicating at itsl lower end with the base ot the next comlmrttnent.

3. ln a pastenrized-liquid holding apparatus, thecombination otl a receptacle provided with inlet and outlet openings, and with a series of normally communicating compartments, a removable stand-pipe applied to the outlet. opening in the rear eompartment', said compartments being provided near their bases 'itli normally closed valved openings all'ording when said valves are opened, a directy conununication 'from one compartment to the next, whereby by the removal o't' the stand-pipe and the opening' of the valves, the contents of the receptacle will [low outwardly through the outlet opening.
